The specific embodiment
Referring to Fig. 1, Fig. 3 and Fig. 4, from the figure as can be seen, the utility model adapts to the variable cross-section anticollision device of pier automatically, by preceding buoyancy tank 1, the back buoyancy tank 2 be connected front and back buoyancy tank stretching device constitute, between buoyancy tank and the back buoyancy tank, stretching device comprised lead, metallic bond, pulley gear and balance crane piece before described stretching device was arranged on; Surrounding on the face of a lead buoyancy tank located therein, another buoyancy tank face of surrounding is provided with the pilot hole corresponding with lead, and lead inserts in the pilot hole and can laterally pass in and out.Lead can be one, also can be the lead group of a plurality of compositions, and pilot hole quantity is corresponding with it to get final product.On the buoyancy tank, the other end strode across the pulley gear 5 that is provided with on the buoyancy tank of back and links to each other with balance crane piece 4 before metallic bond 3 one ends were fixed on; Balance crane piece 4 is arranged in the back buoyancy tank and is in free overhang.Pulley gear makes metallic bond 3 directly not contact with back buoyancy tank wall with balance crane piece 4, thereby protection back buoyancy tank avoids contact to produce the friction damage buoyancy tank, catching phenomenon perhaps occurs, influences the normal folding and unfolding of metallic bond.
The operating principle explanation of two parts buoyancy tank: buoyancy tank 1 and back buoyancy tank 2 surround bridge pier 9 together at ordinary times, and simply be connected with the balance crane piece by metallic bond, being actually the weight of utilizing the balance crane piece draws two parts over to one's side by metallic bond 3, metallic bond 3 is in tension all the time, avoids two parts buoyancy tank freely to suspend and separates; When drawdown, buoyancy tank is inevitable to descend thereupon, if the bridge pier cross section broadens, two parts buoyancy tank can be become big cross section spreading by bridge pier so, the metallic link belt dynamic equilibrium is hung the relative buoyancy tank of piece and is risen, if instead the bridge pier cross section narrows down, two parts buoyancy tank can nature under the pulling force of balance crane piece closes up and is in the state that bridge pier is surrounded all the time, the relative buoyancy tank of balance crane piece this moment whereabouts certain altitude.Buoyancy tank when water level goes up two-part separately or to close up principle the same with its process in the drawdown process.See Fig. 2, Fig. 2 has reflected the freedom deciliter state of buoyancy tank under different water levels.The setting of surrounding face lead and pilot hole only is to guarantee that two parts buoyancy tank can only be in the horizontal direction deciliter, and can not stagger by in the vertical direction, i.e. lifting in any case, and two parts buoyancy tank all is in sustained height.
To be on the safe side, surround between the face also fixedly connectedly by special anticreep chain 6 at front and back buoyancy tank two, piece comes off or when deviating from from buoyancy tank, two buoyancy tanks are unlikely to not connect and freely separate fully, see Fig. 3 and Fig. 4 to prevent to hang.The length of this anticreep chain can guarantee that buoyancy tank can not work the effect of pullling to two buoyancy tanks yet under maximum separated position.At ordinary times, this anticreep chain cuts little ice, and is in the nature overhang, only comes off and just works down hanging piece, is used for the front and back buoyancy tank being linked together and embracing bridge pier.Metallic bond and anticreep chain all should be provided with certain altitude, and it is not submerged in the water, prevent to get rusty.The anticreep chain of every place bonding surface is two among Fig. 3, and totally four on the anticreep chain of two place's bonding surfaces can guarantee bonding strength like this.
Conventional crashproof buoyancy tank adopts the roller stretching structure to adapt to the variation of bridge pier cross section, complex structure, reliability is difficult to guarantee, this crashproof buoyancy tank then adapts to the bridge pier changes of section by the mode that two parts freely surround bridge pier, two parts simply are connected with the balance crane piece by metallic bond draws over to one's side, forms the crashproof floating box structure of on-telescopic.By flow action, even crashproof buoyancy tank all can reliably move under the situation of three face contact operations.Because this buoyancy tank has been cancelled special constructions such as common telescopic guide, flexible bascule, has not only effectively reduced cost of investment, has improved the buoyancy tank operational reliability, and reduced later maintenance intensity and cost greatly.
Be provided with some vertical rubber fenders 7 at preceding buoyancy tank 1 and back buoyancy tank 2 clear widths, whole buoyancy tank utilizes the fender of disposed inboard in the sliding friction operation of bridge pier surface.The structure optimization arch of rubber fender can be born bigger impulsive contact force like this.It is the sliding and running mode that the utility model changes the existing scroll-up/down method of operation, in order to reduce slip resistance, low-friction coefficient high-abrasive material (being polyfluortetraethylene plate in the reality) 8 is installed on the surface that rubber fender 7 contacts with bridge pier, smooth treatment is carried out on the bridge pier surface corresponding with arch rubber fender position simultaneously, as permeate encapsulation process, when reducing friction, can also prevent that sealing infiltrates the inner reinforcing bar of bridge pier corrosion.
But because only single-degree-of-freedom operation of roller, and the pattern of beating a precipitate retreat of the structure after being hit is uncontrollable, be difficult to adapt to rotational characteristic in the plane of crashproof steel buoyancy tank under the flow action, and ship hits the installation push rod of rear roller very likely becomes the arch-criminal of the operational reliability that influences anticollision device, collision-prevention device if can not effectively beat a precipitate retreat, for this reason, the utility model is the sliding and running mode with the roller type optimizing operating mode of routine, utilize the tetrafluoro polyvinyl chloride panel of the inboard fender of crashproof buoyancy tank surface installation and the bridge pier surface sliding and running after the infiltration encapsulation process, adopt this method of operation, but not only multiple degrees of freedom operation, and can effectively improve ship and hit the operational reliability that the back structure takes place accident.In addition, prove that this method of operation is elongated application life, can reduce greatly and safeguard intensity and cost by wear test.
The rubber fender of everywhere vertical direction is made of the two sections that disconnect, and these two sections roughly are positioned at buoyancy tank height 1/3 place and 2/3 place, have avoided the increase of full-scale fender on cost like this, and don't influence is normally slided.
Buoyancy tank main body of the present utility model is a steel work, is constituted and is connected into as a whole by bolt by some cabins.Each independent tank section top is provided with two manholes, is convenient to personnel and enters inside and overhaul.The upstream and downstream end is semicircle arc design in the buoyancy tank outer contour, can change collision course when ship collision takes place like this, avoids positive the collision as far as possible.
The utility model arch fender and bridge pier gap are 50mm, in the day-to-day operation, and the polyfluortetraethylene plate and the bridge pier treatment surface sliding and running that utilize the fender surface to install.Adopt this method of operation, but not only multiple degrees of freedom operation, and can effectively improve ship and hit the operational reliability that the back structure takes place accident.In addition, prove that this method of operation is elongated application life, can reduce greatly and safeguard intensity and cost by wear test.After the generation ship hits accident, utilize the dual distortion of the structure and material of arch rubber fender to contact, thereby cushion energy dissipating greatly with bridge pier.The buoyancy tank main body then utilizes steel pipe to carry out energy dissipating and protection hull in addition.
The utility model can have different malformation according to different bridge pier structure forms, but total design principle unanimity.Reflection is the structural representation of this buoyancy tank protection twin pier on the figure, only needs adaptability revision to get final product for single bridge pier structure.Owing to when the front and back buoyancy tank surrounds, have two and surround face, therefore metallic bond of the present utility model surrounds the face place with the fit structure that hangs piece connected mode, lead and pilot hole at two all setting.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
